Abstract
672,281. Tempering glass. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY & CIREY. Sept. 22, 1949 [Sept. 22, 1948], No. 24381/49. Class 56. A process for shaping a glass sheet comprises subjecting the) glass to a thermal pretreatment before heating the glass prior to shaping it. The pretreatment consists in tempering the glass to modify its viscosity. The glass is then heated rapidly and may be bent to the desired shape.
